Leave slide out?

I would pull them in. You need to exercise the motors and bearings ocasionally and you would unnecessarily be exposing the seals ans wipes to UV rays.

Also if the slides are out I feel it is mor vunerable in a storm.

If it is going to be in Florida I would pull my slides in..Weather conditions, fires etc may cause it have to be moved in a hurry and if the slides are in then it could be quickly moved..Just my opinion and that would make me sleep better at night.

Just my $.03 but I say leave them out. I am in the process of replacing the gear motor of my only slide which will probably run around $1K. The more one uses the slide mechanisms the more likely they are to fail.
After reading the other posts am I allowed to change my answer?
Somehow I had in mind that the poster would be moving the slides every week which prompted the original response.

Some they do,some they dont,and some they just dont care. That;s probably a short summary of the answers you will get...

Actually, I always leave mine out, but it's because it's parked at my house and I go in and out fairly frequent. If I were leaving it elsewhere, I would leave them in.
